Purpose: Adjustment
Function (Purpose): Used to set the default exposure (color
copy) for every document mode.
Section: Scanner
Item: Adjustment
Operation/Procedure
1) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
* The set values can be collectively changed by pressing [V]
[U] buttons.
When the set value is not the upper limit value (lower limit
value), the data of each item is increased (decreased) by 1.
3) When [OK] button is pressed, the currently entered data are
saved to EEPROM and RAM.
* When [↑], [↓], [U], [V] button, [COLOR], or [BLACK] key is
pressed, the data are saved to EEPROM and RAM.
* When [CLOSE] button is pressed, the display is shifted to the
copy basic screen of simulation.
* Copying can be performed also by pressing [COLOR]/[BLACK]
key.

Item: Adjustment
Operation/Procedure
1) When the machine enters Simulation 46-24, the initial screen
is displayed.
When [EXECUTE] button is pressed, the high density process
control is executed and self print of 48 patches is started.
Check to confirm that there is A3 paper on the paper feed tray.
If there is no A3 paper, supply it.
2) While the high density process control is executed, [EXE-
CUTE] button is highlighted.
3) During the self print of 48 patches, [EXECUTE] button is high-
lighted.
4) After completion of the self print, the display is shifted to the
output patch read standby screen.
Place the printed 48 patches on the glass table, and press
[FACTORY] or [SERVICE] button to select the process mode.
5) When [EXECUTE] button is pressed, it is highlighted and the
48 patches set on the table glass are scanned.
Check to confirm that there is A3 paper on the paper feed tray.
If there is no A3 paper, supply it.
6) After reading the patches, self print of 16patches is automati-
cally started.
7) After completion of the self print, the display is shifted to the
registration standby screen. When [REPEAT] button is
pressed, the display returns to the initial screen without exe-

[When [OK] button is pressed, the correction value is saved to
EEPROM and RAM, and the half tone process control refer-
ence value correction is started.
8) The display is shifted to the reference value registration pro-
cess 1 end screen automatically, and the reference value reg-
istration process 2 (BLACK) is executed automatically.
9) After completion of the reference value registration process 2,
the following message is displayed. (Each message is auto-
matically shifted.)
BLACK: 2ND STEP BLACK END

displayed.
10) All the registration processes are completed normally.
* When [CA], [SYSTEM SETTINGS], or [EXECUTE] button is
pressed during self print, the operation is interrupted.

46-25
Purpose: Adjustment
Function (Purpose): Used to execute the fine adjustment of sin-
gle color mode color balance.
Section: Image process (ICU)
Item: Adjustment
Operation/Procedure
1) Select a color to be set. (In this example, [C] (Cyan) is
selected.)
* When a color button ([C](Cyan), [M](Magenta), [Y](Yellow))
is selected, the selected button is highlighted and the adjust-
ment value of the selected button is displayed.
* Only one color can be selected. The selected button is high-
lighted.
In the initial state, [C] is selected.
2) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
3) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
4) When [OK], [↑], [↓] button, [COLOR], or [BLACK] key is
pressed, the current entered value is saved to EEPROM and
RAM.
* When [CLOSE] button is pressed, the display is shifted to the
copy basic screen of simulation.
* Copying can be performed also by pressing [COLOR]/[BLACK]
key.

 
46-26
Purpose: Adjustment
Function (Purpose): Used to reset the single color mode color
balance set value to the default.
Section: Image process (ICU)
Item: Adjustment
Operation/Procedure
1) Press [EXECUTE] button.
[EXECUTE] button is highlighted and [YES] and [NO] buttons
become active display.
2) Press [YES] button.
The single color mode color balance set value is reset to the
default value. [YES] button is highlighted.
* When [NO] button or [EXECUTE] button is pressed, [EXE-
CUTE] button returns to the normal display and [YES] and
[NO] buttons gray out.
* After completion of default reset of the single color mode
color balance set value, [EXECUTE] button returns to the
normal display and [YES] and [NO] buttons gray out.
* The restored data are saved to EEPROM and RAM.

Purpose: Adjustment
Function (Purpose): Used to set the engine gamma calculating
formula coefficient.
Section: Image process (ICU)
Item: Adjustment
Operation/Procedure
1) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
3) When [OK], [↑], [↓] button, [COLOR], or [BLACK] key is
pressed, the currently entered data are saved to EEPROM and
RAM.

Purpose: Adjustment
Function (Purpose): (Information on this simulation may be
requested in some cases. However, this
function is basically not used in the market.) 
Used to check the auto exposure/Auto doc-
ument recognition/ Line number recognition
(Color mode). If the local memory size is
less than 256MB, the operation of this sim-
ulation may not operate normally.
Section: Image process (ICU)
Item: Adjustment
Operation/Procedure
1) Press [EXECUTE] button to start scanning. After completion of
scanning, the result is displayed.
2) Press [NEXT] button to switch to the process data of another
category.
Use [↓] and [↑] keys to change the display page of the process
data.
* If there is a page over [↑], an active display is shown and the
page moves up. If there is no page upward, the display
grays out and the operation is invalid.
If there is a page under [↓], an active display is shown and
the page moves down. If there is no page downward, the
display grays out and the operation is invalid.
3) Press [SETUP] button to return to the initial screen.
* Copying can be performed also by pressing [COLOR]/[BLACK]
key.
* When [CLOSE] button is pressed, the display is shifted to the
copy basic screen of simulation.
* When [NEXT] button is pressed under the final category data dis-
play state, the head category data are displayed.
* Pressing [NEXT] button displays the next category data regard-
less of the display page.
